Abstract

PURPOSE:To prevent the generation of splashes by the ununiform flow of a molten metal which arises in the starting stage by providing a control plate for controlling the flow rate of the molten metal into a molten metal flow passage to a nozzle chip constituting a nozzle slit. CONSTITUTION:This apparatus produces a thin amorphous metallic strip by continuously injecting and supplying the molten metal from the nozzle slit onto the surface of a cooling body under high-speed rotation and quickly cooling and solidifying the same. The flow rate control plate 12 is provided in proximity to the nozzle chip 7 in the expanding part 10 of a nozzle holder 6 for the nozzle slit. The control plate 12 consists of a perforated plate or a filter or a combination of the perforated plate and the filter. The molten metal flowing into the expanding part 10 of the nozzle holder 6 is therefore to collide against the central part of the plate 12, by which the molten metal is branched to the edge part. The branched metal flows out of the nozzle chip 7 at approximately the same speed controlled by the perforated holes.

ている。Among these methods, the Tendésoche method has been adopted in order to enlarge the heating section and enable mass processing. However, in this system in which a stopper is particularly provided, the runner is constricted from the tandem to the nozzle tip having the molten metal spout. An example of the Tendésoche method will be explained with reference to FIG. A tumble push nozzle 4 is provided at the bottom of the tandesh 1 that stores molten metal (molten metal) 2, and an intermediate nozzle 5
, and a nozzle holder 6 are connected to form a passage for the molten metal.

ズル前面に飛散し付着する。As shown in FIG. 6, the nozzle holder 6 has an end of a flow path 9 for molten metal and a widened portion 10 that widens rapidly from the opening of the flow path 9, and the front surface of the widened portion 10. A nozzle tip 7 is fixedly attached to the. As shown in FIG. 5, the molten metal 2 in the tongue pusher 1 is ejected from the nozzle slit 8 through the molten metal channel 9 due to the rise of the stopper 3, and is rapidly cooled by the cooling roll R to form a ribbon (metal thin strip). 11 is formed. However, since the molten metal flow path 9 is narrow at this time, the flow velocity of the molten metal increases and a large amount of molten metal spouts out at the center as shown in Fig. is separated into three parts as shown in the same figure (g)). Next, when the hot water pressure in the entire spreading group increases, a merging occurs between the molten metal flows (■) and (2), resulting in a steady state shape. Collision of the molten metal occurs when the molten metal flows merge. This uneven vortex flow phenomenon at the start causes the molten metal to collide at the tip of the nozzle, resulting in a splash that scatters and adheres to the front surface of the nozzle.
